I have a Sharp LC37D44U and I was watching it when it shut off and the power + OPC lights flash 2x each then the OPC light flashes 3x, not sure what this means, I cannot find any info on this anywhere. Anyone know?

I have been able to get sound after unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in which should have put it in SERVICE MOD. but the picture is blank, I can see the backlight is on but no picture.

The link above may point to the service manual; the service manual is also on Scribd.

The failure codes are listed on pages 6-14 and 6-15. This appears to indicate failures in the 3.3V and UR6V supplies. The 3.3V supply is generated on the main board from the 5V supply, I didn't notice where the UR6V supply comes from.

The power supply schematic is not included. As a first step, look at the labels on the connectors of the power supply.

Well I have taken it in to be looked at and well it aint gonna be cheap, about $900.00 to repair, so I am working on getting Sharp to repair or replace the TV under warranty, so far it looks like they might.

Well Sharp has offered me an LC40D68UT as a replacement @ $285.00. As much as I am not happy about it, it is cheaper then buying a new TV from a store. Oh the LCD screen on the old one has a short, that is what the repair shop has found, so I am trying to find someone that might have a dead TV that I can steal parts from, but I ain't holding my breath

Well I have kept that TV around all this time and I just came across an LC-32D44U that the sound quit on, so after doing some research I found that this TV uses the same Mainboard as the LC-37D44U and since the 37" has a toasted LCD panel I swapped the mainboard and boom, sound fixed on the 32", so I guess it paid off to keep it around all this time.
